Looks like you haven't really read my post.
I require a low profile video card, and one that doesn't take too much power.
The ones you posted are full blown monsters from the looks of it, and I have no way of using them in such a small case that I have. Remember I have only 220 watts to play with, which isn't a lot to begin with.
Oh yeah, I do have PCI-E 1.0 according to what I've seen. The booklet isn't any help. Even if I do have PCI-E 1.0 even 2.1 cards are supposed to work.
